The examples that Thomas Shinder or any body else gives to configure
dcomcnfg.exe do not touch upon configuring any port under "Default
Protocols" under TCP/IP when dcomcnfg.exe is run.

I have followed his examples exactly. I have added Everyone to "Custom
Access permissions", "Custom Launch Permissions", "Custom Configure
Permissions" and done all other configurations.

However I have to do this this extra configuration for our mail to be
received. I have  to add port 25 as an internet port - not as intranet -
for mail sent to our domain to be received. Why is there this further
facility to configure TCP/IP? When I add Port 25 as an internet port, all
other ports except Port 25 appear under Intranet ports!!!!  Ports 1-24 and
Ports 26-... appear as intranets ports . What does this mean?  I  have
already run the Secure Mail Server Publishing Wizard and configured it to
listen on Port 25. This extra bit of configuration under TCP/IP under
Default Protocols is really confusing !!! More so because nowhere does any
one touch upon it. Our SMTP server that receives our mail is internal.

Any explanation will be greatly appreciated.
